Distribute That
Use the Distributive Property to solve.
5 x 8 =
( _ x 8) + ( _ x 8) =
(1 x 8) + (4 x 8)
8 + 32 = 40
(2 x 8) + (3 x 8)
16 + 24 = 40

Mark is having a party. He invited 35 people. Mark set up 8 tables with 4 chairs at each table. Does Mark have enough tables and chairs for all his guests? Explain using words and numbers.
No, Mark does not have enough because 8 tables with 4 chairs is 8 x 4 which equals 32. He needs three more places for his guests.
